Florida UV Index by City
Florida's low latitude and abundant sunshine make it one of the higher-UV states in the country, from Jacksonville down to Key West. Choose your city below for a labelled typical hourly reference and a location-aware current-UV check.
Because Florida sits at a low US latitude, UV runs high across the state and climbs as you move south, with Key West, Miami and Fort Lauderdale typically peaking above more northern Jacksonville. The index tops out midday and is strongest from late spring through early fall, often reaching the EPA very high (8+) band, and the WHO advises protecting from UV 3 and up. Each linked city page starts with a labelled typical reference and shows current and forecast UV only after a usable response; these are estimates to manage burn risk, not a promise of a safe tan or medical advice, and water, sand and sweat can raise real exposure.

Each city page starts with a labelled typical clear-sky reference for Florida and replaces it only after a usable current UV response. Failed requests remain visibly labelled as reference data. Estimates only — not medical advice.
Questions
Which Florida city has the highest UV?
The southernmost cities, Key West, Miami, Fort Lauderdale and Naples, generally see the highest typical peak UV thanks to their low latitude and strong sun angle, frequently hitting the EPA very high (8+) band on clear summer middays. Jacksonville and Orlando run high too but are usually a notch below the far south. Bright water and white sand reflect additional UV, so use each city page's current-UV check before acting. These are estimates, not medical advice.
When is UV lowest in Florida?
UV is typically lowest early morning and late afternoon, and seasonally in the winter months when the sun is lower, though Florida's low latitude means winter middays can still reach the EPA moderate-to-high range. The EPA notes UV 3+ is common even off-peak here, and clouds, reflection off water and sand, and sweat can change real exposure. Use each city page's labelled reference for orientation and its current forecast after a usable update.
Is it safe to tan in Florida at midday?
Florida middays (roughly 10am-4pm) routinely sit in the EPA high (6-7) or very high (8+) bands, so the WHO guidance to protect from UV 3+ strongly applies and burn risk peaks then. No tan is truly safe because tanning is UV damage; if you're outside, the FDA recommends broad-spectrum SPF 30+ reapplied every 2 hours and after swimming or sweating, plus shade and protective clothing. Our tanning-time numbers are risk-managed estimates, not medical advice, and your Fitzpatrick skin type, medications, water and sand reflection all change actual risk.
